Where to Farm Common Materials?

Basically the prices of the materials sold at the material traders are too high
and i was wondering if anyone new a good place to farm:

Glittering Dusts
Tanned Hide Squares
Bolts of Cloths
Wood Planks
Iron Ingots
Chintin Fragments
Bones
Granite Slabs
Feathers

I know a good place to farm bone is killing the Undead in the D'Allessio Seabord mission.

thanks

The best place to farm bones:
Shattered Ravines the quest farming aka dead sword farm. ~20 mins makes about 150 bone. Or more.
Glittering dust: djinn farming in hidden city of idontknowwhat in NF. When they drop dust, the drop 32 if I remember well, u can get tons of them. Easiest with 130hp dervish.

Glittering Duist: FoW, UW, Kessex Peak
Tanned Hide: Arborstone
Bolts of Cloth: Arborstone
Chitin: outside Ascalon City
Wood: Trolls outside Droknar's Forge (salvage staffs and bows)
Bones: Dead Sword quest
Feathers: Naphui Quarter

i wouldnt farm dust in FoW or uw the enemys are hard to kill solo and they have a 10% chance to drop 4 dust

Dust: fow/ uw
Hides: ettin armour from kryta ettins
Cloth: kournan soldiers in kourna or salvaged from deccayed orr emblems
wood: staffs and bows in fow/uw
Iron: from swords and axes and one handed weapons in fow/uw
Chintin: insects in kourna
bones: undead on gok and nebo terrace (these undead also drop decayed orr emblems which salvage into cloth)
Granite: kirin from around the kruzick forest
Feathers: lots of these drop from star tengu in naphui quarter (i got 50 once from one run with hench) also you can salvage the scalps from the avica in the southern shiverpeaks.
